Question;125. The slope of a horizontal line is infinite, and the slope of a;vertical line is zero.;126. The slope of a line is the ratio of the vertical distance covered;to the horizontal distance covered along the line.;127. If a line passes through the points (20,5) and (10,10), then the;slope of the line is 1/2.;128. If a line passes through the points (20,5) and (10,10), then the;slope of the line is -2.;129. Changes in one variable on a graph might be caused by the other;variable on the graph or by a third omitted variable.;130. Deciding that A causes B when in fact B causes A is a mistake;called omitted variable bias.
